Change Spine Texture in Runtime (Cocos Creator 3.8)

Hello.

My spine skeleton has lots of textures. I have several png files on export from Spine program.
Most of this png file I need only on endgame. That’s why I want to load this png files in runtime. Is it possible? I can’t understand how to set loaded texture to skeleton.

I tried to test it on one png file like this.

this.skeleton.skeletonData.textures = [this.texture];

But this approach doesn’t work. Sprites from new texture don’t want to refresh and are still pink.
What is the best way to do it?
